Name derivation:
Oxalis from the Greek 'oksos' meaning sour; referring to the taste of the leaves and stems caused by the oxalic acid, especially the flowering stalks of Oxalis pes-capraePerennans from the Latin 'per' meaning through and 'annus' meaning year; referring to the perennial nature of the species.
Distribution:
Found across South Australia, especially in the southern part, growing in a very wide range of habitats. Also found in all states (and New Zealand).
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Perennial herb to 30 cm high with erect, ascending or sometimes creeping stems above ground but rarely rooting at nodes, sparsely to densely hairy. Leaves cauline with 3 leaflet, which are cuneate-obcordate, to 15 mm long and wide, green, bilobed, glabrous to pubescent above, pubescent or hairs confined to midrib below. Inflorescence 1-6  yellow flowers per stalk held above the leaves. Flowers throughout the year.
Fruit type:
Pale brown cylindrical capsule  to 30 mm long and 2.5 mm diameter, densely hairy.
Seed collecting:
Collect capsules before they are fully matured, those turning pale brown and contain hard seeds. When fully mature, the capsules bust open explosive dispersing the seeds up to a few metres from the parent.
Seed cleaning:
Place the capsules in a tray and cover with newspaper to prevent the seeds from flying out as the capsule dries. Then rub the capsules gently with a rubber bung to dislodge the seeds. Use a sieve to separate the unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place
